Red-headed Woodpecker!?

Pleasant morning at Nahanton. Mary Lou was already there when I arrived at 8:10. We found a Yellow-throated Vireo in the trees at the back of the upper garden. I had the Blue-headed Vireo above the raspberries at the lower garden, and while wewere there what could only have been a Red-headed Woodpecker flew over. I returned alone later to the lower garden and found the Lincoln's Sparrow.
